Saint-Petersburg Underground rail network, or 'Metro' as it
is universally known to visitors and inhabitants of the city,
and it is normally the quickest and easiest way of travelling
around Saint-Petersburg. Saint-Petersburg metro has been
open since November 15, 1955. Due to the city's unique
geology, the Saint Petersburg Saint-Petersburg metro is
considered to be one of the deepest subway systems in the
world and the deepest by the average depth of all the
stations. The system's deepest station Admiralteyskaya, is
105 metres below ground. Serving two and a half million
passengers daily, it is also the 13th busiest subway system
in the world.
Some of the features of the Saint Petersburg Metro make
it stand out amongst others, even those in the former USSR.
It is customary to have stations in the centre of a city built
very deep, not only to minimise disruption, but also, because
of the Cold War threat, they were built to double as bomb
shelters, and many old stations do feature provisions such
as blast doors and air filters. However, in most cities, the
lines become shallow or even begin to run above ground
as they reach the city's outer residential districts. However,
this is not the case in Saint Petersburg. The difficult geology
means that 56 out of 63 stations are at a deep level. The
design and architecture went through numerous phases.
Saint-Petersburg metro system has five lines
Kirovsko-Vyborgskaya Line which is the oldest line of the Saint Petersburg Metro, opened in 1955.
Moskovsko-Petrogradskaya Line is the second oldest line of the Saint Petersburg Metro, opened in 1961. It
featured the first cross-platform transfer in the USSR. It was also the first metro line in Saint Petersburg to
feature a unique platform type that soon became dubbed as "Horizontal Lift".
Nevsko-Vasileostrovskaya Line is a line opened in 1967. Since 1994, it has been officially designated as
Line 3. It stands out among St. Petersburg metro lines for two reasons — its stations are almost exclusively
of "Horizontal Lift" type and it has the longest inter-station tunnels in the entire system.
Pravoberezhnaya Line is a line opened in 1985, it is the shortest line in the system with the stations featuring
a modern design. Since 1994, it has been officially designated "Line 4," but the original name is still often
used in informal context.
Line 5 of Saint Petersburg Metro, also known as Frunzensko-Primorskaya Line, connects the city's historical
centre to the northwestern and southern neighborhoods. The line is being extended from both ends as of
